🛠️ Key Components

Backend Components

API Layer (backend/api/)

SEO Dashboard API:

# backend/api/seo_dashboard.py
@app.get("/api/seo-dashboard/data")
async def get_seo_dashboard_data():
    """Get complete SEO dashboard data."""
    return await seo_service.get_dashboard_data()

Blog Writer API:

# backend/api/blog_writer/router.py
@router.post("/research/start")
async def start_research(request: BlogResearchRequest):
    """Start research operation."""
    return await research_service.start_research(request)

Models (backend/models/)

Database Models:

# backend/models/user.py
class User(BaseModel):
    id: int
    email: str
    created_at: datetime
    subscription_tier: SubscriptionTier

Pydantic Models:

# backend/models/requests.py
class SEOAnalysisRequest(BaseModel):
    url: str
    target_keywords: List[str]
    analysis_type: str

Services (backend/services/)

Business Logic:

# backend/services/seo_analyzer.py
class SEOAnalyzer:
    async def analyze_url(self, url: str) -> SEOAnalysis:
        """Analyze URL for SEO performance."""
        # Implementation here

Frontend Components

React Components (frontend/src/components/)

SEO Dashboard:

// frontend/src/components/SEODashboard/SEODashboard.tsx
export const SEODashboard: React.FC = () => {
  const [dashboardData, setDashboardData] = useState<SEODashboardData>();
  // Component implementation
};

Blog Writer:

// frontend/src/components/BlogWriter/BlogWriter.tsx
export const BlogWriter: React.FC = () => {
  const { research, outline, sections } = useBlogWriterState();
  // Component implementation
};

Custom Hooks (frontend/src/hooks/)

API Hooks:

// frontend/src/hooks/useSEOData.ts
export const useSEOData = () => {
  const [data, setData] = useState<SEODashboardData>();
  // Hook implementation
};

📊 Development Workflow

Getting Started

Development Setup:

# Clone repository
git clone https://github.com/your-org/alwrity.git
cd alwrity

# Backend setup
cd backend
python -m venv venv
source venv/bin/activate  # or venv\Scripts\activate on Windows
pip install -r requirements.txt

# Frontend setup
cd ../frontend
npm install

Running Development Servers:

# Backend (Terminal 1)
cd backend
uvicorn app:app --reload --host 0.0.0.0 --port 8000

# Frontend (Terminal 2)
cd frontend
npm start

    response = client.get("/api/seo-dashboard/data")
    assert response.status_code == 200

Frontend Testing:

// src/components/__tests__/SEODashboard.test.tsx
import { render, screen } from '@testing-library/react';
